I'm fully aware that my vision of a European bicameral parliament can't be implemented tomorrow. I'm also not an integration fanatic.
Europe was founded as a community bound together by solidarity.
I'm proud of the fact that Marine Le Pen in France insults me and Geert Wilders in the Netherlands calls me his opponent. The way I see it is, if these people weren't attacking me, I would be doing something wrong.
We have committed ourselves to pursue joint policies, but then national governments say, "We aren't bound by that." That is a dramatic situation, because solidarity is a basic principle that cannot be had on an à la carte basis. If we have rules that nobody adheres to, then the community will break apart.
My worry is that Donald Trump may inspire copycats, also in Europe. That's why I hope Hillary Clinton wins.
I believe that the majority of people in Europe want to demonstrate solidarity with the refugees.
Now Europe are experiencing a wave of eroding solidarity, first of certain societies and then entire governments. At the same time, we have two giant new challenges to meet: the migration movement and terror. And then Great Britain is thinking about leaving the EU. That should suffice as a description.
If you say in advance there is going to be a main candidate and then that doesn't count later, then that's going to be a highly problematic occurrence in a democracy.
You have to let the people vote when it comes to a new constitution.
Without new money, salaries won't be paid, the health system will stop functioning, the power network and public transport will break down, and they won't be able to import vital goods because nobody can pay.
I firmly believe that the inequity [in society] is enormous. The people have the feeling that you are allowed to do anything if you are rich. But if you're poor, you have to pay. We [Europeans] have to counter this.
Turkey is doing an enormous amount in the refugee question, but it can't continue to pay for everything by itself. That is why we have to talk to Turkey about money.
Things are going well in Germany because the economy is booming and as an export-driven nation, we are profiting from the fact that we have an excellent, high-performing SME sector. But if we want things to continue to go well into the future, then we have to break up the antiquated structures in some areas and really modernize.
The EU is a community of values, not military buildups.
We need a big debate in society about how we are going to shape Europe and tame capitalism. A government must provide direction and make concrete proposals. It is one of Angela Merkel's biggest failings that she doesn't do this.
Donald Trump has made the principle of purposely breaking a taboo into a means of achieving his political objectives, which is something that he has in common with Turkish President Recep Tayyip Erdogan and Hungarian Prime Minister Viktor Orbán. Trump systematically violates international rules. But we cannot allow ourselves to forget that Trump is not the U.S.
You can't always be demanding solidarity from others and then refuse to show it yourself.
The old fundamental principles must continue to apply, even in our changing society: Democracy knows neither master nor slave. Equal education opportunities for all, no matter where they come from and no matter who their parents are. Equal access as well when it comes to digitalization.
The construction of social housing and the attempt to support families seeking to buy their own homes are all projects from the 1960s and '70s. It all sounds old-fashioned, but it is actually completely modern.
It's not attractive at the moment to vouch for the European idea. I still do it, because I believe nothing would be better for our continent.
The membership survey was a great moment for inner-party democracy. We can't go back, nor do we want to. Our members are pouring their hearts into this campaign. But people don't join the Social Democrats party just to put up posters. They join because they want to help steer the party.
We are seeing now that without the contribution of the Social Democrats, Germany cannot be governed. We are a proud and self-confident party. We should now act based on that pride, and not out of fear.
In all of my speeches I talk about why a strong Europe is necessary in order for Germany to be strong over the long term. I think that I have sufficiently shown over the past years that I have a clear notion of how we can make Europe stronger, more democratic and more inclusive. There is really no competition there with Sigmar Gabriel.
If we no longer judge the content of people's actions, but merely their form, then we are entering dangerous times indeed.
I would have oriented myself in case of Donald Trump according to what former German Chancellor Gerhard Schröder said to then - U.S. President George W. Bush when the Americans launched a war that was in violation of international law. Schröder showed that a German chancellor can act in a clear and self-confident manner toward a U.S. president.
